COVERED ROLLER FOR COTTON=EVIACHINES.

SPECIFICATION forming part of Letters Patent No. 701,266, dated May 2'7, 1902. 1

Application filed December 3, 1900. $erial No. 38,596. (No model.)

States, have invented a new and useful Improvement in Covered Rollers for Cotton- Yarn Machines; and we do hereby declare that the following is a full, clear, and exact description of the invention, reference being had to the accompanying drawings, making a part of this specification, in which Figure l is a longitudinal front View of the entire improvement. Fig. 2 is a longitudinal sectional view through from w 00. Fig. 3 is a perspective view of the improved roller. Fig. 4 is a longitudinal front view of the spindle to which the rollers are secured for their use.

Our invention relates to improvements in covered rollers for cotton-yarn machinesoperated in connection with a spindle; and the objects of our improvements are, first,to lessen the expense of recovering the rollers when worn; second, the detaching of the same therefrom; third, to reduce the cost in transportation by the lightness thereof. We attain these objects by the mechanism illusstrated in the accompanying drawings,which we may now proceed to describe.

Similar letters of reference indicate corresponding parts.

The roller A, Fig. 3, is made of some suitable light material, wood being preferable. A hole is drilled longitudinally through its center of the required size to fit tightly upon either end of the spindle B, Fig. 4:, and may be held firmly thereon by providing said spindle with a right and left hand screw-thread, as shown in the drawings, and with a corresponding thread in the roller A, or, as we now prefer to carry out this feature of our invention, washers O O are fitted to either end of spindle B by means of a shank extending into and held therein and'against the rollers end by a screw-head, the screw portion of which passing into the ends of said spindle B, as represented in sectional view Fig. 2. The

central portion of the aforesaid spindle B is provided with a spool-shaped bearing for the opposite ends of said rollers to rest against, and in securing the aforesaid rollers the required distance apart for their use, as represented in Fig. 1, square ends are formed on the rollers,which contact with the square ends of the spool and the flange c of C.

The roller A being formed of wood, as hereinbefore described, the outer or periphery surface is first covered with woolen cloth, over which is secured a leather covering for its finish and use, by which means we form a durable roller at much less cost than the necessary expense now incurred in recovering the ordinary iron rollers when theircovering becomes worn, and even in re-covering the same wooden roller when injuredfrom its use and being made separate fromthe spindle it maybe attached or detached, as occasion may require--a great advantage in the use of our improved roller. They maybe held in stock at a trifling cost, and their lightness renders them less expensive in transportation than the heavy iron roller now in use. Furthermore, they may be used as a shell-roller, wherein the spindle is held stationary from turning byinserting a metallic tubular bushing into its center of the proper size, the whole fitted to revolve loosely upon the ends of the stationary spindle.

To are awarethat prior to our invention covered rollers have been made and used in cotton-yarn machines. We therefore do not claim covered rollers broadly; but

'W'hat we do claim as our invention, and desire to secure by Letters Patent of the United States, is

A top roll for use in cotton-machines, which comprises a spindle having a spool with squareends formed integraltherewith at its center,a roller having a covering of cloth and an outer covering of leather mounted on each end of said spindle, said rollers having square ends engaging the ends of the spool their other ends extending in vertical alinement with the ends of the spindle, a washer carrying a flange and a shank, the shank being secured inthe ends of the spindle with the flange engaging the outer end of the roller, and a screw countersunk in said washer extending through the shank and secured in the spindle, substantially as described.
